Definiční obor funkce
Urči definiční obor funkce:
\( \large e:y = \ln \left[ 8x\left( 1+x\right) -8x^{2} +4 \right] \)
\( \large D\left( e\right) = \left( 0\large ;\infty\right) \)
\( \large D\left( e\right) = \left( -\Large \frac{1}{2}\large ;\infty\right) \)
\( \large D\left( e\right) = \left( -1\large ;\infty\right) \)
\( \large D\left( e\right) = \left( -\Large \frac{1}{3}\large ;\infty\right) \)
